This report identifies managed networks with the highest ratios of poor-quality Teams calls focusing only on network-level data so that an admin can isolate and fix local network issues under IT control — even for peer-to-peer calls — and improve end-user experience. It mainly uses metrics that point to network specific problems:
- Call Setup Failures
- Mid Call Failures
- Sent Quality Event Ratio
- ReceivedQualityEventRatio
Benefits of using the Page ?
- Identify Managed Networks with Network related Call Problems
- Analysis of sending / receiving streams on Devices on the Network. Are outbound issues more common than inbound, or are they balanced?
- Starting Point to drill-down into Managed Network Details to see all relevant information about a Network
What
Two main items determine the criteria for listing networks.
Calls where more than 2% of Streams showed quality degradation events
Calls experiencing Call Setup Failure or Mid Call Failure
What are these metrics underneath ?
- sentQualityEventRatio: Percentage of streams where the sending endpoint reported quality affecting events (like high jitter, packet loss, or even CPU issues).
- receivedQualityEventRatio: Percentage of streams where the receiving endpoint reported quality affecting events.
- CallSetupFailure: Client has problems to establish a connection to join a Teams Call
- MidCallFailure: The client was disconnected or received a message that Teams is attempting to reconnect to the meeting.
Examples
- High sent ratio + low received ratio: Problem likely on the user’s outbound path (local network, Wi-Fi, VPN, or device CPU).
- Low sent ratio + high received ratio: Problem likely on remote user’s outbound path or your inbound network.
- Both high: General network issue (e.g., corporate WAN, ISP ,...). Device is unlikely the reason.
Components on the Page
The Time Picker allows users to specify a particular timeframe. Please note that if a period longer than 14 days is selected, the data will be capped accordingly. In this case, the original start date is retained, and the end date is set to 14 days after the start date.
KPIs
- % User Calls Impacted: Percentage Ratio of Total Number of User Calls across all identified and potentially impacted managed networks vs. Impacted User Calls
- Impacted User Calls: Total Number of Impacted User Calls across all identified managed network. Impact means that one of the mentioned condition is true
- Mid Call Failures: Number of User Calls with Mid Call Failures
- Setup Call Failures: Number of User Calls with Setup Call Failures
- Firewall Block Exception: Number of User Calls where MissingFWIPBlockExemptionRule got triggered. The issue could be related to either firewall and network reasons or other events where the call setup was unsuccessful.
- Non-Standard Audio Port: Number of User Calls using non-standard audio ports
Grid
Clicking a network row opens the Managed Network Details dashboard with more detailed Information about the selected Network
- Network ID: Subnet Network Id (e.g. 10.0.10.0/24)
- Networkname: If network name information is provided, the name of the corresponding network is displayed
- Country: If network name information with Country is provided, the Country is displayed
- City: If network name information with City is provided, the City is displayed
- User Calls: Total Number of User Calls on this Network
- % Impacted User Calls: Percentage Ratio of Total Number of User Calls on the Network vs. Impacted User Calls
- Sent Quality Event Ratio: Average Percentage Ratio of Sent Quality Event Ratio across all User Calls
- Received Quality Event Ratio: Average Percentage Ratio of Received Quality Event Ratio across all User Calls
- Setup Call Failures: Number of User Calls with Setup Call Failures
- Mid Call Failures: Number of User Calls with Mid Call Failures
- Firewall Block Exception: Number of User Calls where MissingFWIPBlockExemptionRule got triggered. The issue could be related to either firewall and network reasons or other events where the call setup was unsuccessful.
- Non-Standard Audio Port: Number of User Calls using non-standard audio ports
